Zusammenfassung:	The utility model discloses a corrosion-resistant bolt which comprises a bolt body, the bolt body comprises a bolt head and a screw rod, a groove body penetrating through the side edge of the bolt body is formed in one side of the bolt head and one side of the screw rod, and a zinc block detachably connected with the groove body is arranged in the groove body. According to the utility model, the zinc block with higher activity is arranged on the bolt body, and the zinc becomes the negative electrode of a primary battery and is continuously corroded due to the fact that the zinc is more active than steel by utilizing the reaction of the primary battery; according to the anti-corrosion bolt, the zinc block and the groove body are detachably connected and can be replaced at any time, the situation that the anti-corrosion performance of the whole bolt is affected after the zinc block is corroded is avoided, the first rubber sealing edges matched with the sheet body are arranged on the two sides of the sheet groov
